Re: Help - Green clear water - Problems Again

Hi Mass;

All sequestering agents are temporary in their effect, so the improvement in your water is also temporary. However, if the CuLater works as advertised (we're not sure yet), it's the only product that can remove metals (iron, in your case) from the water even while it's sequestered.

We hope it does work as advertised -- it would be a very useful tool for quite a few people. But, you'll want to watch. They claim a color change as the material captures metal from the water. Also, once the iron begins to be released from the sequestering agent, it will begin to stain things. If you run your pump continuously, what it's likely to stain is your filter (which is OK) and the interior of your skimmer. So, you may want to watch for that.

Good luck . . . and please let us know how it goes. (We'd like to know if the CuLator product DOES work.)

Re: Help - Green clear water - Problems Again

Just thought I'd leave an update. My pool has remained blue over the last three weeks. I did add sequestering agent once - one morning I detected the beginning of a greenish tint in the water (and added the sequestering stuff) and by the evening it was back to pure blue. I have not had to add any fill water, as we have had plenty of rain.

Re: Help - Green clear water - Problems Again

Thanks so much for the info. I'd really like to get a better understanding, this year, of how metals behave in pools, and responses like yours really help.

I wonder if you could do 3 things:

(1) Tell me how you've been testing. (Do you have a K2006, TFP100 or ?)
(2) Tell me what sequestering agent you used.
(3) Do white bucket tests on both the pool water and your fill water - to see if metals remain in either one.

First two are easy, of course. If you're willing to do bucket tests, here's how it goes:

1. Get a clean white 5 gallon bucket
2. Add 4 gallons of test water (do the pool first, fill water second)
3. Add 1/4 cup each of plain bleach and 1/8 cup of baking soda to the water, and mix till the soda is dissolved.
4. Cover and wait 2 days -- leave the bucket where it won't be moved or disturbed.
5. Check for sediment on the bottom, especially color.
6. Tell me what you find.

Re: Help - Green clear water - Problems Again

(1) I use the Taylor K-2006 test kit

(2) I use Clearview Mineral Magnet (by OREQ) sequestering agent.
(Note: At the beginning of the season (over the course of a week) I used three bottles of Natural Chemistry Metal Free and it did not get my pool to turn blue. I am not sure whether I had so much metal in my water, because I added so much fill water when I opened the pool, that it didn't reach the tipping point with the Natural Chemistry MF or whether the Natural Chemistry isn't effective. Anyway I switched to the Clearview Mineral Magnet and the pool turned blue in a couple of days.)

(3) Haven t had a chance to do the white bucket test

My pool has remained blue over the last six or seven weeks, but I haven't had to add any fill water (lots of rain)

My CuLator pack floated in the skimmer for about five weeks - and then sank to the bottom of the skimmer basket
